You get given enough time to try various methods of extraction.", "@paddygr : I'm referring to the latest FRTE 1:N report, specifically section 3.5, which states, \"We do not report FTX...\". Given this, I assume the numbers reported in Table 15 under the column \"failure to extract features\" are only FTE – the proportion of templates that could not be generated during enrollment. My follow-up question concerns the IREX10 submissions: Does the FTE Rate reported on the table on the website also refer to the proportion of template generation during enrollment?" ]

[ "Can you use a relative RPATH instead? You can also change your RPATH to '.' or whatever is relevant with `chrpath`", "Hi @xsacha \r\n\r\nThanks for the prompt response.\r\n\r\nSo, here is how my lib is structured\r\n\r\n\r\n\r\nI have tried the following options in my CMakeLists.txt file in the src/nullImpl folder\r\n\r\n```\r\n# Option 1\r\nset (CMAKE_SHARED_LINKER_FLAGS \"-Wl,-rpath-link,$ORIGIN/opencv_42/lib\")\r\n\r\n# Option 2\r\nset (CMAKE_SHARED_LINKER_FLAGS \"-Wl,-rpath,$ORIGIN/opencv_42/lib\")\r\n\r\n# Option 3\r\nset(ocv_name opencv_42)\r\nset(CMAKE_SHARED_LINKER_FLAGS \"-Wl,-rpath-link,${CMAKE_CURRENT_SOURCE_DIR}/../../lib/${ocv_name}/lib/\")\r\n\r\n#Option 4\r\nset(ocv_name opencv_42)\r\nset(CMAKE_SHARED_LINKER_FLAGS \"-Wl,-rpath,${CMAKE_CURRENT_SOURCE_DIR}/../../lib/${ocv_name}/lib/\")\r\n```\r\n\r\nWhen I do chrpath, I can see that the rpath is set appropriately as expected\r\n\r\n\r\n\r\nAlso the libraries for libopencv_dnn, libopencv_imgproc etc. are present in the proper locations as seen below\r\n\r\n\r\n\r\nHowever when executing the `run_validate_11.sh` file, these libraries are not fetched...\r\n\r\nCould you suggest how can I debug this issue further? I have tried several things but nothing has succeeded so far...\r\n\r\n", "I would say your chrpath is showing that the RPATH is misconfigured. For example if you move the library to another path, does it still work? It looks like a full path in the output.\nYou can also change the rpath to a relative path.\n\nTry this: move the libraries and bin to a different path as the validation would do and then check if it works. If it works, no problem.", "Thanks for the comment, indeed it was misconfigured.\r\n\r\nNow I think it is configured correctly as I can see that it is showing origin correctly in the rpath of the exeutable.\r\n\r\n\r\n\r\nHowever, still some opencv libraries are not being picked up despite their presence in the libs folder as shown in the following folder structure\r\n\r\n\r\n\r\n", "Hi @xsacha ,\r\n\r\nIf I do an ldd to check if all the libraries are linked properly against the submission library, I get the following output\r\n\r\n\r\n\r\nIt is linking with all the libraries properly except `libopencv_imgproc.so`, any ideas why would that be? The library exists in the same path as `libopencv_dnn.so` and `libopencv_core.so` which are there in the same directory as `libopencv_imgproc.so`.\r\n\r\nAny idea on what might be going wrong? This same thing works fine when I test on my local machine but on the VM built using ISO provided by NIST, I encounter this issue...\r\n\r\nThanks,\r\nVinayak.", "Solved this issue. After inspecting which files are not linked to my submission library I found that the opencv libraries were not linked and this was happening because the LD_LIBRARY_PATH was set only to frvt/11/lib.\r\n\r\nKeeping all the opencv libraries in lib folder in a flat format helped solve this issue.", "@ElisonSherton Can you give some hint on how you changed the CMakeLists.txt since I am facing the same issue as well. My folder structure inside lib folder is as follows:\r\nlib:\r\n libfrvt_nullimpl.so\r\n opencv_folder\r\n onnxruntime_folder\r\nopencv and onnxruntime \".so\" files are inside the opencv_folder/build/lib and onnxruntime_folder/build/Linux/Release/ folders respectively.\r\n\r\nAlso did you set the ldd_library_path to frvt/11/lib and moved all the opencv libraries to that folder? If so then how did you edit the cmakelists.txt?", "Hey @rishidd11,\r\n\r\nIf you're facing the same issue as me, then this may help you.\r\n\r\nLD_LIBRARY_PATH is already set by NIST to point to the `frvt/11/lib` folder [as seen here](https://github.com/usnistgov/frvt/blob/b6b23da12b8d814d96a63e69179133e6972c20e2/11/run_validate_11.sh#L23), so I did not manually change it or make any changes to CMakeLists.txt for linking purposes. I do assume that libs are stored in the `frvt/11/lib` location and accordingly set my paths.\r\n\r\nInstead from the opencv_folder/build/lib (as in your case), I took all of the .so files and kept them inside the `frvt/11/lib` folders. That made my code work as expected.\r\n\r\nHope this helps.\r\n\r\nThanks,\r\nVinayak." ]

[ "In the updated protocol that supports multiple faces detected in an image, we take the maximum similarity score across all template comparisons between each enrollment and verification image pair. The high ranks (poor FNMR) are due to higher FMR under the max(score) policy. The upside to this approach is of reduced FNMR – this can occur because in a genuine comparison of say an image with 1 face present with another image with 2 faces present, detection of the correct mated person was not guaranteed before we changed the API. With the new API, one of the two faces should score highly. We take largest score over those produced in comparing K1 templates from image 1 with K2 templates from image 2, i.e. max of K1 * K2 scores. We do this for mated **and** non-mated comparisons." ]

[ "All the main frameworks such as tensorflow, pytorch and mxnet have been known to work in NIST.\r\nYou may just need to compile it differently or set it up (usually a setting in each framework) so it does not attempt to use multi-threading.", "Okay, I'll see if it is a multi thread problem and if I can recompile it without multi-threading.\r\nAlso, I'm closing this issue for now.", "Hi NIST team.\r\nI've searching a lot and sadly, I've had the same problem. \r\nI even migrated my TF Rust code to CPP with no luck.\r\n\r\nResearching a little more I foud an open issue regarding NIST implementatinos in the official TF github and they say as follows:\r\n[https://github.com/tensorflow/tensorflow/issues/51832#issuecomment-926205545\r\n](https://github.com/tensorflow/tensorflow/issues/51832#issuecomment-926205545)\r\nSo basically NIST API is not compatible with all model inferences with TF and the TF developers have not intenssions to make TF fork safe.\r\n\r\n¿Do you have any plans to make more compatible your API with TF?\r\nFor me it's contradictory that you use forks when TF, one of the more spreaded IA framekors, is not fork safe.\r\n\r\nI've seen that TF allows \"sessions\" as servers, and \"session-clients\". But that will require an extra process to use it. I assume that that implementation is not allowed by NIST.", "We've received a number of submissions using TF. It's possible to move your model initialization to the child process (after the fork) and invoke it once during the first API call. As for measuring timing, we consider and report the median time across thousands of API calls (e.g. createTemplate()), so even if your very first API function invocation takes longer, it should not impact the timing benchmark.", "Thanks. That was my first approach, but TF in Rust takes a long time to initialize. In c++ the initialization is faster.\r\nNow I'm initializing at \"matchTemplate\" once per fork.\r\n\r\nJust as conclussion for this issue. If you initialize your TF model at \"initialize()\"w and it hangs at \"matchTemlate\", you should try to initialize it once per fork at \"matchTemplate\" or \"createTemplate\". Regarding the time, it may not affect considerably the benchmark due the mean calculatiuon of thousands of API calls.\r\n\r\n¿Am I right?\r\n\r\n" ]
